In his letter, Plytnykas says: “I have refused to serve my sentence in your county.

“It is only a first impression that Scotland is a fair and rich county. In reality, that’s not the case.

“Human rights are breached. There are lies and fakeness all over the place. In your prisons, I have spent six years.

“During that term, your prison staff and other people have breached human rights every day.”

Perth jail may not have been up to Plytnykas’s standards. But after he was deported in March, he found out to his cost that being in the slammer in his home country is far worse.

Conditions in Lukiskes jail in Lithuanian capital Vilnius are grim. Plytnykas has no work, no chance to earn money and no TV.

In 2011, a journalist described cells as having a “hole in the corner” as a toilet for two inmates.

Plytnykas says: “Conditions are poor. There is no work or job, living conditions are bad and I do not have a family who would help me out from outside.

“I don’t even have a basic TV, so I can’t watch the news. I have no money to buy anything.”

The killer’s hope of having his sentence cut were also quashed when a Lithuanian court upheld the life sentence imposed in Scotland.

Plytnykas is now pleading for his belongings to be returned to him in Lukiskes jail.

His letter says: “When they deported me, my personal belongings were not passed over to Lithuania and I need these items badly.

“Prison staff are obliged to send my personal belongings to me.

“Because they have sent me from one prison to another, they also have to send these items together with me. It’s their job.”

In his letter, Plytnykas also claims his conviction is based on “false statements” which he promises to explain to the Record if we agree to meet him.

Plytnykas and Aleksandras Skirda killed Jolanta, 35, for her money.

The pair bound, gagged and suffocated her at the flat she shared with Skirda after forcing her to give them access to £10,000 savings she had amassed for her grandmother’s cancer treatment in Lithuania.

The killers chopped up Jolanta’s body and dumped it in the sea.

During Plytnykas’s trial, the jury were shown CCTV footage of the killers on a bus to Arbroath carrying a plastic Lidl bag containing their victim’s head and hands.

They also saw footage of the pair dragging a suitcase containing Jolanta’s body through the town.

Her head was found washed up on Arbroath beach by two young sisters. Her hands were later discovered on the same beach.

Skirda, then 20, admitted the killing and gave evidence against Plytnykas.

Skirda was given 20 years, but this was later reduced to 18 years.

When he was in Perth jail, Plytnykas, who lived with wife Laima and daughter Samantha, now seven, in Scotland, was attacked several times and went on hunger strike.

Plytnykas wad held in Barlinnie prison in Glasgow on his way to deportation.

A source there said his belongings, including jewellery, had been sent on to the authorities in Lithuania.

The Scottish Prison Service said: “We ensured that all Mr Plytnykas’ items were signed for and returned to him as part of his repatriation.”
